Explanation:
Detailed explanation-1: -The neuromuscular junction (NMJ) is a synaptic connection between the terminal end of a motor nerve and a muscle (skeletal/ smooth/ cardiac). It is the site for the transmission of action potential from nerve to the muscle.
Detailed explanation-2: -Final answer: The space between the muscle cell and nerve terminal is called the neuromuscular junction.
Detailed explanation-3: -Cell membranes of motor nerve terminals and muscle fibers are separated by a space called the synaptic cleft, which is approximately 30 – 50 nm. In the synaptic cleft, acetylcholinesterase is concentrated to hydrolyze the neurotransmitter acetylcholine to terminate each synaptic transmission.
